ok guys, i dont know why this seems to work, but on the same computer I installed Win 7 alone and the game did not work, however, when i dual boot Win XP and Win 7 with XP on the primary partition OR install Windows 7 as an upgrade to XP rather than a custom install, the game works fine. I think it has something to do with the way it uses the display drivers. Try manually downloading the proper display driver and if it has an accelerator driver get it. If u have an intel board its pretty easy, dont know about AMD.
